DAVID A. KENNEDY, OF LEXINGTON, VIRGINI A, ASSIGNOR OF ONE-HALF TO JOSEPH KENNEDY, OF SAME PLACE.

MEANS FOR SECURING THE CUTTERS OF HARVESTERS TO THE CUTTER-BARS.

SPECIFICATION formingpart of Letters Patent No. 269,062, dated December .12, 1882.

' Application filed June 6, 1882. (No model.) I

T all whom it may concern Be it known that 1, DAVID A. KENNEDY, a citizen of the United States of America, residing at Lexington, in the county of Rockbridge and State of Virginia, have invented certain new and useful Improvements in the Means for Securing the Gutters of Harvesters to the Gutter-Bars; and I do hereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to which it appertaius to make and use the same.

This invention relates to improved means 'for securing the cutters of harvesters to the 1 cntterbars; audits object is to provide a simple and reliable means for attaching singly each cutter in such manner that each cutter may be attached and released independently of the others.

My invention therefore consists in a harvester-cutter having the shank made with the usual beveled edges, and formed with a beveled wedge-shaped recess in the rear of the shank, forthe purpose hereinafter set forth. My invention further consists of a cutterbar of a harvester provided with the usual beveled recesses on its face to receive the cutters, and formed with vertical wedge-shaped recesses in the rearside registering with the 0 wed ge-shaped recess in the cutter.

My invention further consists in the novel construction, combination, and arrangement of parts, as will be hereinafter .more specifically described and claimed. In the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view of the cutter-bar, cutter,

and fastening-key. Fig. 2 represents the cutter; and Fig. 3 is a perspective view, showing 0 the parts joined.

The letter A represents the cutter-bar havin g-cut or formed in its upper face the transverse beveled recesses it to receive the shanks of the cutters, and formed with beveled wedge 5 shaped recesses b in the rear face of the bar,

centrally located in the transverse beveled recesses in the face. 7

The letter B represents the cutter, formed, so far as the blade is concerned, as'may be desired, and having the shank made with beveled edges fitting the beveled recesses in the cutter-bar, and also formed with a. beveled wed ge-shaped recess, 1) in the rear of the shank corresponding to the beveled wedge-shaped recesses formed or cut in the rear side of the 5 cutter-bar.

The letter 0 represents a wedge made with beveled edges and fitting flush in the recesses of the shank of the cutter and cutter-bar.

It will be observed that the vertical recesses of the cutter-bar are made slightly flared at the lower portions, the object being to admit of slightly spreading the key on the lower side, so as to prevent it from working out, and yet not sufficient to prevent'its being drawn out and used again. To better secure the cutters to the cutter-bar it is advisable, after the key is driven home, to upset the metal thereof by hammering or otherwise, so as to fill the angles of the cutter and cutter-bar, substantially as seen in Fig. 3 of the drawings, to prevent any displacement of the fastening-key; but the upsetting should not be of such positive char 'acter as to prevent theremoval of the key for I do not claim broadly the construction of the v I cutter-bar with transverse beveled recesses in the upper face, nor the cutters formed with the shanks beveled to fit the transverse recesses of the cutter-bar, as both of these have been heretofore in use; but my invention is to form 0 vertical beveled wedge-shaped recesses in the rear of the cutter-bar'and shank of the cutter adapted to receive and retain a wedge or key beveled on the edges.

By the means herein described and shown 5 the cutter and bar are held from displacement in every direction and under all circumstances, whether the strain be upward or downward,

forward or rearward, and. the combination of parts secured as stated meets every exigency which can reasonably happen.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. A harvester-cutter the shank whereof is formed with beveled edges and a verticallybeveled wedge-shaped recess in the rear of the shank, substantially as described, and. for the purpose set forth.

2. A harvester cutter-bar formed with beveled recesses on its face adapted to receive the shanks of the cutters, and formed with verticall y-beveled wed ge-shaped recesses in the rear face thereof, substantially as described, and for the purpose set forth.

3. The cutters provided with beveled edges and vertically-beveled wedge-shaped recesses in the rear of the shanks, in combination with the cutter-bar having vertically-beveled Wedgeshaped recesses on the rear side, and wedgeshapcd keys adapted to fit in the verticallybeveled wedge-shaped recesses of the cutter and bar, substantially as described.

In testimony whereof I affix my signature 25 in presence of two witnesses.

DAVID A. KENNEDY.
